DoF!

Whilst enjoying this view towards Kawakawa Bay from Waitawa I noticed the flowers in the following shots.

Whilst enjoying this view towards Kawakawa Bay from Waitawa I noticed the flowers you can see in the following shots.

Out for a walk at the regional park I spotted a rather lovely looking bloom … is it a wildflower or an escaped exotic? I only had my 24-70mm lens with me … wifey not keen on me taking lots of gear with me when we’re supposed to be having a walk! The question then … do I shoot to isolate the bloom from the background, or do I let you see a little more of the view in the image as well?

Two images below for you to consider. The first image has the lens stopped down to f10 to get a reasonable Depth of Field (DoF). In this shot the clouds, the Coromandel Peninsular and the sea have a bit of detail, but not too much to detract from the bloom. By opening up the lens to have a larger aperture (smaller f-stop) it’s possible to reduce the detail in the background and can be seen in the second shot.

This second shot was taken with the lens wide open at f2.8. Now there’s significantly less detail in the background and the flower stands out more. Just a few clicks of the aperture ring, and two quite different images. Just curious, but which do you prefer?
